[jjup13]

hello everyone,
when i using qwebengineview to load a website called www.taobao.com, sometimes the site need me to slide a slider, so it can check if i'm a robot. but when i try to slide in qwebengineview, it always fail. and this website work very well on chrome.

my system is windows10, my qt is 5.11.3, and i tried 5.12.0, the problem is still.

so, if somebody help me find out is there anything different from chrome can cause this. I will appreciate very much.
